Abstract

The process and assembly may join two or more pieces of material (1-3), one a very strong profile, and the other an ultra-strong profile. The join accepts and transmits all loads, forces and moments up to a predefined level without structural degradation. The union is effected by choice of suitable materials and treatment processes, plus a choice of suitable design. The components are joined by suitable bonding materials, adhesives, special solder etc.

Description

Das Verfahren und die Vorrichtung zur Verbindung hoch- und höchstfester Profile hat die zerstörungsfreie und deformationsarme Aufnahme und Übertragung aller auftretenden Belastungen, Kräfte und Momente bis zur vorgegebenen Größe zum Ziel.The method and the device for connecting high and ultra-high strength profiles has non-destructive and low-deformation recording and transmission of all occurring Loads, forces and moments up to the specified size to the goal.

Wenn die hoch- und höchstfesten Profile ihre speziellen Festigkeitseigenschaften durch eine Strukturveränderung mittels einer Wärmebehandlung erhalten haben, sind sie nicht oder schlechtschweißbar, weil durch den Wärmeeintrag beim Schweißen die gewollten festigkeitsverbessernden Strukturveränderungen zumindest in den der Schweißbehandlung angrenzenden Bereichen wieder verloren gehen.When the high-strength and ultra-high-strength profiles pass through their special strength properties have received a structural change by means of heat treatment, they are not or poorly weldable, because the heat input during welding means the desired strength-improving structural changes at least in the Welding treatment adjacent areas are lost again.

Die alternativen Verbindungen zur Schweißverbindung von Profilen werden im wesentlichen durch:
The alternative connections to the welded connection of profiles are essentially through:

  • 1. Durch geeignete Materialauswahl und/oder Materialbehandlung sowie durch die konstruktive Gestaltung der Verbindung;1. Through suitable material selection and / or material treatment and through constructive design of the connection;
  • 2. Durch die Auswahl geeigneter Verbindungsmaterialien und Verbindungsmedien sowie deren Aufbringen und Behandeln bis zum Erreichen des gewünschten Endzustandes;2. By selecting suitable connection materials and connection media as well their application and treatment until the desired final state is reached;
  • 3. Durch die Auswahl und Anwendung geeigneter physikalischer, chemischer und anderer Behandlung der unter Pkt. 1. genannten Materialien der Verbindung selbst, als auch der unter Pkt. 2. genannten Verbindungsmaterialien und Verbindungsmedien;
    erreicht.    3. Through the selection and application of suitable physical, chemical and other treatment of the materials of the connection mentioned under point 1, as well as of the connecting materials and connection media mentioned under point 2;
    reached.

Der gegenwärtige Stand der Verbindungstechnik (ohne Schweißen):
The current state of connection technology (without welding):

  • - Es ist möglich, die Verbindung für hoch- und höchstfeste Profile durch ein spezielles Verbindungsteil (z. B. ein zugeschnittenes Blech oder Profilstück ) herzustellen, welches genau so, oder ähnlich mit Wärme behandelt wird, wie die Profile selbst. Dadurch werden ähnliche Festigkeitswerte, wie bei den hoch- und höchstfesten Profilen erreicht. Da Schweißen nicht möglich ist, sind Schraub- oder Nietverbindungen anwendbar, aber sehr arbeitszeitaufwendig und dadurch mit sehr hohen Kosten verbunden.
    Die marktüblichen Schrauben und Niete sind auf Grund ihrer, für die hoch- und höchstfesten Profile zu geringen Festigkeitswerte, gegenwärtig für Verbindungen nicht geeignet. Das betrifft auch die Querschnittsschwächung der hoch und höchstfesten Profile durch die notwendigen Bohrungen mit zu großen Durchmesser.    - It is possible to create the connection for high and high-strength profiles using a special connecting part (e.g. a cut sheet or profile piece), which is treated with heat in exactly the same way or similarly as the profiles themselves. This results in similar strength values , as achieved with the high and highest strength profiles. Since welding is not possible, screw or rivet connections can be used, but they are very labor-intensive and therefore very expensive.
    The commercially available screws and rivets are currently not suitable for connections due to their low strength values for the high and extremely strong profiles. This also affects the cross-sectional weakening of the high-strength and high-strength profiles due to the necessary holes with too large diameters.
  • - Preßverbindungen der hoch- und höchstfesten Profile könnten durch entsprechend vorbereitete Profilenden realisiert werden, die durch einen entsprechenden Druck miteinander verpreßt werden, einschließlich anderer Arten von Fügen. Da die hoch- und höchstfesten Profile wesentlich schwerer zu verformen sind, wie die bisher verwendeten Profile, wären wesentliche Änderungen notwendig, damit dieses Verfahren für die hoch- und höchstfesten Profile angewendet werden kann.- Press connections of the high-strength and ultra-high-strength profiles could be achieved accordingly prepared profile ends can be realized by appropriate pressure pressed together, including other types of joints. Since the high and ultra-strong profiles are much more difficult to deform than those previously used Profiles, essential changes would be necessary for this procedure for the high and ultra-strong profiles can be applied.
  • - Das Kleben von Profilverbindungen wäre mit den bisher verwendeten Klebstoffen und -me­ dien aufgrund der zu geringen Festigkeit, besonders durch kleinere Flächen durch geringere Bauhöhen, nicht möglich.- The gluing of profile connections would be with the previously used adhesives and -me serve due to the insufficient strength, especially due to smaller areas lower heights, not possible.

Im weiteren werden die hoch- und höchstfesten Profile zum besseren Verständnis nur noch als Profile bezeichnet.In the following, the high and highest strength profiles are only for better understanding still referred to as profiles.

Beispiel 1example 1

Zwei Profilenden, die tiefgekühlt sind (z. B. mit flüssigen Stickstoff), werden in eine normal temperierte, entsprechend vorbereitete Hülse eingesetzt und dehnen sich beim Erwärmen auf Raumtemperatur aus und erzeugen damit eine Preßverbindung (Schema siehe Fig. 1). Diese Verbindung von Profilen ist nur anwendbar wenn durch die starke Abkühlung keine ungünstige Material- oder Strukturveränderung entsteht. Weiterhin ist zu prüfen, ob diese Verbindung auch beim Einsatz unter extremen Temperaturen den auftretenden Belastungen standhält.Two profile ends, which are deep-frozen (e.g. with liquid nitrogen), are inserted into a sleeve with a normal temperature and suitably prepared and expand when heated to room temperature and thus produce a press connection (see diagram in Fig. 1). This connection of profiles can only be used if there is no unfavorable change in material or structure due to the strong cooling. It must also be checked whether this connection can withstand the loads that occur even when used under extreme temperatures.

Beispiel 2Example 2

Drei Profilenden werden in eine entsprechende vorbereitete Hülse eingeklebt. Der Klebstoff ist so auszuwählen, daß er die entsprechenden Kräfte und Momente zerstörungsfrei von einem Profil zum anderen Profil überträgt. Wenn es die Gesamtkonstruktion erlaubt, kann die Hülse aus normalen Material hergestellt sein, und wäre dann auch schweißbar. Das würde aber an dieser Stelle den Verzicht der Vorteile der Profile bedeuten, wie z. B. geringere Abmessungen.Three profile ends are glued into a corresponding prepared sleeve. Of the Adhesive should be selected so that it has the appropriate forces and moments transfers non-destructively from one profile to another profile. If it is Overall construction allows, the sleeve can be made of normal material, and would then also be weldable. But that would mean giving up the advantages at this point the profiles mean such. B. smaller dimensions.

Es wäre möglich, anstelle der beiden stumpf gestoßenen Profile ein durchgehendes Profil einzusetzen, wenn es die Gesamtlänge o. a. Umstände es erlauben.It would be possible to use a continuous profile instead of the two butted profiles to be used if the total length or the like Circumstances allow it.

In Fig. 2 ist diese Verbindung schematisch dargestellt.This connection is shown schematically in FIG .
